Hi, I can rewrite your existing plugin functionality following API instructions from kashflow.
Please check my ratings and feedbacks to see the proof of my experience and expertise in Wordpress. There are more than a hundred of excellent reviews and all of them are rated 5 out of 5 with 98% completion rate, that is rare case when ALL employers were fully satisfied! That means I always seek for perfection, please compare to other freelancers with their average rating of 4.8/4.9 and ~80% completion rate.
I have successfully completed hundreds of different WP projects starting from minor theme or content updates to huge and complex WP plugin development and dozens of external API integration tasks. I have 11 years experience in Web Development, 6 years with Wordpress. Comparing to other freelancers who are spamming with their bids I am actually reading your project description and bid with precision only on projects I like.
I am located in Latvia, North Europe and I work mostly with employers located in Europe and North America.
